value of 1 in this bit means
that an input state change of
Input 1 was missed due to the
transmission of a higher
priority message.
2 Bit (5) = Missed Input 2.
value of 1 in this bit means
that an input state change of
Input 2 was missed due to the
transmission of a higher

Byte 5 = Longitude
Byte 6 = Longitude LSByte
360 degrees of Longitude coded

in signed binary with 3 bytes
and 180 degrees of Latitude
coded in signed binary with 3
bytes.
Positive Longitudes correspond
to East Longitudes
Positive Latitudes correspond
to North Latitudes
These bits reflect the state of
the inputs and indicate which
one, if any, triggered an Input
